- Formula For Recovery In Mineral Processing
Mineral processing - Concentration, Separation, Flotation: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical …

The overall concentration process may be subdivided into one of liberation, which severs the bonds between unlike mineral species, and another of separation, which sorts the resulting liberated particles into two products, a concentrate, rich in mineral "A", and a tailing, lean in mineral "A".

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …
